A method for detecting a calibration board includes providing a vehicle-mounted panoramic camera and a first type of calibration board, wherein an upper surface of that first type of calibration boardis provided with a mark point; acquiring an initial image captured by a vehicle-mounted panoramic camera; identifying a mark dot in the initial image and overlaying the first mark block at the position where the mark dot is identified as the mark dot; judging whether the first marker block covers the marker dot, if the first marker block covers the marker dot, then, obtaining the center coordinates of the mark points to determine the initial external parameters of the vehicle-mounted panoramic camera; if the first mark block does not cover the mark points, adjusting the surrounding environment of the first type calibration board, obtaining the images captured by the vehicle-mounted panoramic camera again, and carrying out the next cycle until the first mark block covers the mark points. The method is convenient for the operator to judge whether the identification of the position of the mark dot is accurate or not and to conveniently find the disturbing object caused by wrong identification in the environment, which is helpful to improve the calibration efficiency, save the calibration time and improve the calibration precision.

The invention discloses an air conditioner, a control method and device of the air conditioner and a readable storage medium. The air conditioner comprises at least two air return ports formed in different positions, temperature sensors arranged at the air return ports to collect the air return temperatures of the air return ports, and a controller used for determining the reference temperature according to the air return temperatures of the air return ports and controlling the running state of the air conditioner according to the reference temperature. According to the air conditioner, the control method and device of the air conditioner and the readable storage medium in an embodiment of the invention, the air return temperatures of the air return ports in different positions are detected in real time, the reference temperature used for controlling running of the air conditioner is comprehensively determined according to the multiple detected air return temperatures, automatic adjustment of the running state of the air conditioner is achieved, and normal work of the air conditioner is guaranteed.

A method for detecting a calibration board, comprising: providing a vehicle-mounted panoramic camera and a first type of calibration board, the first type of calibration board is provided with mark dots on the upper surface; obtaining an initial image captured by the vehicle-mounted panoramic camera; identifying the mark circle in the initial image Points, cover the first mark block at the position of the mark dot identified and judged; judge whether the first mark block covers the mark dot, if the first mark block covers the mark dot, then obtain the center coordinates of the mark dot to determine The initial external parameters of the vehicle-mounted panoramic camera. If the first mark block does not cover the mark dot, adjust the surrounding environment of the first type of calibration board, and obtain the image captured by the vehicle-mounted panoramic camera again, and enter the next cycle until the first mark Block cover sign dots. The invention is convenient for the operator to judge whether the position recognition of the mark dot is accurate, conveniently finds the interfering objects in the environment that cause misidentification, helps to improve the calibration efficiency, saves the calibration time, and improves the calibration accuracy.
